90s pop tune Na nananaaaaa ...
Im almost sure that the name of the song is CHILDREN (or has the word in the title).
And the song begins with 'mother and father...'
I can't remember any lyrics, just the chorus that goes something like 'na na na naaaaa - na na na naaaaaa' sung by children-like voices.
The singer was a guy, or at least sounded like one.
I think it was released in the early 90s.
